Abstract

L'invention concerne un procédé d'intégration d'un dispositif de commande à fonction d'auto-verrouillage, qui comprend la commande de moteur et résout les problèmes techniques actuels de faible fiabilité et de mauvaise confidentialité des données existant dans un auto-verrouillage effectué par un dispositif auxiliaire. Ledit procédé consiste à : réaliser un repère de verrouillage dans un dispositif de commande ; recevoir une instruction de commande d'auto-verrouillage, et si l'instruction de commande d'auto-verrouillage est une instruction de déverrouillage, configurer l'état du repère de verrouillage en tant qu'état de déverrouillage ; si l'instruction de commande d'auto-verrouillage est une instruction de déverrouillage, configurer l'état du repère de verrouillage en tant qu'état de déverrouillage ; lorsque le dispositif de commande reçoit un signal de désactivation d'interrupteur à clé, valider une fonction de retard de désactivation et sauvegarder l'état du repère de verrouillage ; lorsque le dispositif de commande est activé la fois suivante, celui-ci lit l'état du repère de verrouillage sauvegardé la dernière fois ; et le dispositif de commande commande le fonctionnement d'un moteur en fonction de l'état du repère de verrouillage. Le dispositif de commande change et sauvegarde l'état du repère de verrouillage en fonction de l'instruction de commande d'auto-verrouillage, et effectue un auto-verrouillage ou un déverrouillage sur le moteur en fonction de l'état du repère de verrouillage, avec une haute fiabilité et une bonne confidentialité.
